Disgusting lack of service from Telkom!!!

We are really disgusted in your lack of service. In July we changed over to Telkom fibre, and the technician who installed it told us that he would cancel the extra phone line, the ADSL which we had been using prior to the fibre, and the Callmore Service, we didnt have to worry. Lo and behold, none of these services were cancelled, and we got a ********** bill for fibre PLUS these extra services, I phoned to cancel it, and was told by the agent to send an email, which I did. I got a response from Telkom that the services would be terminated, and yesterday I got the new billing from Telkom, and these services are STILL BEING CHARGED!!! I emailed Telkom again, expressing my disgust, and I got an email to say it has been sent to the relevant department. I am not getting any service, and they ignore my instructions to cancel the services. This has been going on since July, and we refuse to pay for them again. We want to be credited for August and September billing on the services the technician promised would be cancelled in July .... this is really disgusting and I am so furious that I have to waste even more time sorting this out when I thought it would be cancelled after the email exchange ..... Where to from now??? I have no clue.
